PUNCH.

Specification of Letters Patent.

Patented Sept. 12, 1916.

Application filed August 22, 1913. Serial-No. 786,067.

To all whom t may concern:

Be it known that I, THOMAS E. HEETER, a citizen of the United States ofAmerica, residing in the city of St. Louis and State of Missouri, haveinvented certain new and useful Improvements in Punches, of which thefollowing is a specification. j

This invention relates more especially to punch presses used forpunching holes in loose leaves which are used in loose leaf prongbinders, and has for its primary object to provide improved meanswhereby both single and double holes for all sizes of standard prongbinders can be punched with this improved device by a slight adjustingof parts. l

Other and further objects will appear in the specilication, and bespecifically pointed out in the appended claims, reference being had tothe accompanying drawings exemplifying the invention, and in which,

Figure 1 is a front elevation of this improved punch. Fig. 2 is a rearelevation of Fig. 1. Fig. 3 is a plan view of this improved device. Fig. 4 is a transverse section taken on the line IV-IV, Fig. 1. Fig. 5 isa transverse section taken on the line V-V, Fig. 1.

Referring by numerals to the acompanying drawings: 1 designates the mainframe, which is preferably bent into form from one piece of material,and comprises a base 2, an elevated horizontal portion 3, a bent returnhorizontal portion 4, a vertical portion 5, and a top horizontal portion6. Secured to the rear of said main frame 1, and adjacent each end, areend supports 7. Located adjacent the center of said frame at the rearare a pair of'central supports 8. Secured to said main frame adjacentthe center, and at the rear thereof, and between said central supports8, is a brace plate 9. Said brace plate has a bearing 10 formed the-reinadj acent the top for the reception oit' an oscillating member' 11. Saidmember 11 has a shoulder 12 formed thereon which bears against the frontside of the plate 9, and a shank portion 13 on which a handle 14 isfmounted. Said handle is held against movement on said shank portion byriveting a head 15 on said shank. Formed integral with said member 11 isa crank 16, said crank having an annular groove 17 formed thereon.Formed on the front edge of each end support 7, above the top 6 of theframe 1, are vertical cutaway portions 18. At the top of each cut-awayportion on said end supports isformed a lug 19.

Formed'in the portions 3, 4, and 6 of the main frame 1 are a series ofcircular openings 20, all of said openings in said portions being invertical alinement with each other. liteciprocably mounted in thevertical cutaway portions v18 are protruding ends 21 of a head 22, saidhead having an elongated opening 23 formed therein adjacent the centerthereof.` Said opening is adapted to be engaged over the crank 16 of theoscillating member 11. Pivotally mounted at 24 to the front side of thehead 22 is va retaining latch 25, said latch having an elongated opening26 formed therein through which the pivot 24 is mounted. Formed adjacentone end of said latch is a recess 27. This latch 25 is for the purposeof holding the head 22 on the crank 1 6, the recess 22 engaging over thegroove portion 17 of said crank after said crank has been inserted inthe elongated opening 23 of vsaid head. Formed in said head 22 adjacentthe lower edge are a series of elongated openings 28, each of saidopenings adapted to aline vertically with the circular openings 20formed in the portions 3, 4 and 6 of the frame 1. Adapted to reciprocatein the series of `vertically alined openings 20 are a pair of punches29, each of said punches having a transversely recessed portion 30formed therein adjacent the top, thus forming a lip portion 31 on saidpunches. Said lip portion is for the purpose of securing saidpunchesto'the head 22 by inserting said lip portions in the elongatedslots 28 of said head.

Formed in 'each of the supports 7 and 8 is an opening 32, said openingsbeing in horizontal alinement with each other, and are `for the purposeof supporting the rear leg 33 of a gage member 34, said gage also havinga front leg35 and an abutting portion 36. Pivotally mounted at 37 on'theinside of one of the end supports 71's an eccentric lever 38, whichlever, when'pressed"down-` wardly, is adapted to bite'the rear leg 33 ofetI pairs of holes. This improved device is operable in conjunction Witheither type of binder.

In theV operation of this improved device, if kit -is desired to punchsingle pairs of Vholes in sheets that are required for binders of thelargest` single pair type, the punches 29 are insertedr into vthe seriesof circular openings A. In order to do this, the head 22 must be removedfrom its operating position, which removal is brought about by elevatingthe latch 25 and then pulling said headoff the crank 16. Then the lips31 Yof said punches are inserted in the openings A', and the head 22 isagain mounted onY the crank 16, and the latch 25 Y Ydropped into itsnormalposition. v The gage 34is'V set sothe abutting portion 36 thereofWill abut one edge of the sheets to be punched. v Y Y If it is desiredto punch holes inv sheets for the medium size single pair binder, thepunches'29 are removed and are inserted in the series of openings B, andthe lips 31 of said punches are inserted in the openings B of said head22. If it is desired to punch holes for the smallest type of single pairbinder, the punches 29 are inserted in the series of openings C, and thelips 31 thereof are engaged in the openings C of said head 22. Y Thiscompletes the rearranging of parts to accomplish thev punching of holesY in different sizedY sheets for the three different types of singlepair binders novv in use.

When it is desired to punch holes in sheets for Vbinders that requiredouble pairs of holes, one of the punches 29 is engaged in the series ofalining openings D, and the lip 31v thereof is inserted in the opening Dof the head 22. The other punch 29 Vis inserted in the series'ofvertical alining openings E, and the lip 31-thereof is inserted in theopening E of the head 22. Y

The double pair binders are also of three sizes, and to accomplish thepunching of holes for one of said sizes of binders a master sheet isfirst made. This is done by folding a sheet ofpaper on itslongitudinal-center, and the centerV fold thereof is alined with theYgage line F. Then the handle of the punch is manipulated. Then thesheet is Withdrawn and opened out. This punching struck out the mastersheet. Novv the master sheet is placed upon a number of sheets which areto be punched, and the gage 34 is manipulated to have the abuttingportion 36 thereof to one edge of the sheets in ac- Y cordance With thepunches matching the holes on one side of the sheet Which has alreadybeen punched. The handleY of the punch is again manipulated and a pairof i .holes are Vpunched through the sheet in accordance With the holesof the master sheet. ThenV the sheets of paper are Withdrawn, and thegagel 34 is reset so as to match the punched holes of the master sheetWith the punches so that pairs of holes can be punched through theremaining sides of the sheets.

In making a master sheet for the medium size binder, the folder line ofsaid sheet is alined with the gage line G, and the same operation isfollowed as just described relative to the punching of the sheet for thesmallest binder. And for the largest binder, the folded line of themaster sheet is alined With the gage line II, and the operation isfollowed up as before.

It is to be noted vvhen sheets are to be punched they are inserted inthe aperture 39 Which is formed between the horizontal portions 3 and 4,and the ends of the sheet Will abut against the rounded portion 40. Thenthe handle 14 is manipulated, and the punches are forced dovvnvvardlylthrough the sheets. When the manipulation of said handle is reversed,the punches are drawn upwardly from the sheets.

What I claim is:

1. A paper punch comprising a frame, provided vvith a series of holes, apair of removably mounted punches reciprocably mounted in said holes, aremovable head reciproeably mounted above said holes, a series of slotsformed in said head, said slots of said head being for the reception ofthe upper ends of said punches, and providing means for securing saidpunches to said head, said head during its reciprocation forming meansfor actuating Said punches in a pair of said holes.
